dump of gpu error state
Just seen this GPU-hanger once, will report back if it occurs again. The
application was in the system tray and when I tried to open the window, the
system seemed frozen for several seconds.

[145347.575540] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[145347.575540] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[145347.575540] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[145347.575541] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
